About This Book

Through a series of lectures the author advances a mutation theory proposing that new species and varieties originate by sudden jumps from existing forms while the parent type remains unchanged; such mutational events may arise singly or in groups and at diverse times. The work contrasts this view with gradual-change explanations, surveys experimental and historical evidence, and outlines pedigree experiments and cultivation methods designed to make the origin of species an object of direct study. It examines variability, inheritance, and selection, highlights gaps in knowledge, and suggests practical approaches for further investigation.

About the Author

de Vries, Hugo portrait

Hugo de Vries

Hugo de Vries was a Dutch botanist and geneticist, best known for his pioneering work in the field of evolution and heredity. He introduced the mutation theory, which proposed that new species arise from sudden genetic changes rather than gradual evolution. His influential book, "Species and Varieties, Their Origin by Mutation," laid the groundwork for modern genetics and had a significant impact on the study of evolution. In addition to his scientific contributions, de Vries wrote on various topics, including natural history and geology, as seen in his works like "Het Yellowstone-Park" and "De aardbeving van San Francisco." His research continues to resonate in contemporary biological sciences.
